FOLDING REEL FOR HARVESTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 366,114, dated July 5, 1887.

Application filed Apr 14, 1857. Serial No. 233.579. No model.)

To aZZ whom it may concern.-

Be itknown that I, HENRY KELLOGG, a citizen of the United States, residing at New Haven, county of New Haven, in the State of Connecticut, have invented a new and useful Improvementin Folding Reels for Harvesting- Machines, of which the following is a specification, reference being had to the accompanying drawings.

The object of my invention is to secure a reel which shall be capable of expansion and contraction to meet the requirements of different heights of grain to be cut, and which shall also be capable of being folded into a small compass when not in use and duringtransportation and storage. v

A further object of my invention is to secure a reel which shall be capable of expansion and contraction by the expenditure of a smaller amount of force than has heretofore been necessary in reels of this class.

My improved reel may be employed in different types of harvesting-machines.

In the drawings, Figure 1 represents a reel constructed according to my invention, ex-

The upper part of the figure represents a plan view of one of the heaters and its connecting parts. The lower part of the figure represents an isometric view of one of the heaters and its connect ing parts, while at the right of the figure is shown, in dotted lines, a representation of the reel in its folded condition. Fig. 2 represents an end view of my improved reel. Fig. 3 represents the fork connecting the folding mechanism with the rack and pinion.

a is the reel-shaft, which is revolved by the spur-wheel a by means of a worm or any other suitable means. At a the reel-shaft is provided with a universal joint, and at its other or outer end has its bearings in a piece, (0 the upper portion of which is hinged at a so as to be capable of being thrown back, to permit of the reel-shaft being taken out of its bearing to be swung out of the way on the universal joint at a a is a pin, which secures the two parts of the piece a when the reel-shaft is in operation.

I have shown in the drawings, Fig. 2, five heaters, b, b, b, If, and b, but do not mean to confine myself to a reel employing that exact number, as a greater or less number may be 'mizing space.

usefully employed. The means for operating any one of these heaters to open it, adjust it, 7

or fold it up completely is the same as is used for all, and therefore a description of one will suffice, it being here stated that all the heaters are operated for all purposes simultaneously.

I will describe the beater Z) and its operating parts. The beater consists of a strip of wood, and it is connected to the reel-shaft by a pair ofjointed arms pivoted to the beaterone near each end. Each one of these jointed arms is made up of two members, cand c, which are of equal length. The member 0 is composed of two parts, 0 and 0 as shown in Fig. 2 and in the lower beater, if, of Fig. 1.

As is shown in Fig. 2, the member a of each pair ofjointed arms is connected with a piece, d, of which there are two. Each of these pieces is rigidly secured to the shaft a, as shown in Fig. 1, and has five logs or projections such as are shown-in connection with the piece in Fig. 2, and to these lugs the parts 0 and c of the jointed arms are pivoted. This method of connecting the jointed arm with the shaft secures strength in its inner member, and as the outer member is pivoted between the parts of the inner member it also affords a pocket for a portion of the outer member. to lie in when folded, thus econojointed arm is pivoted a strip, 6, at a point about one-third of the entire distance of the beater from the reel-shaft when fully expanded. I have found in practice that-by pivoting'the stripe at about the point named the reel may be folded in a smaller compass than have reels of this class heretofore. I have found that in a reel of seven feet possible expansion, by 10- cating the strips 6 at the point shown in the drawings,the heaters will not,.while being expanded or contracted, move out of line endwise more than from two and a half to three inches, and that when closed the boaters will project beyond the point they occupied when fully open little if any. Each of the strips e is connected at its inner end with the reelshaft by means of a piece, e, rigidly secured to the reel-shaft. These pieces 6 are, in their general form, similar to the pieces (1, having five lugs upon their surface, to which thestrips for each beater are respectively connected.

While I prefer to use two strips 6 for each To the outer member of each.

-beater, one only maybe used and good reconnect the two upper members, although I do not recommend thislatter. The real function of the stretcher f being to maintain the same relative distance between the jointed arms, and to secure their simultaneous operation,the place and manner of mounting them can be varied considerably.

g is a short stud or arm mounted on the inner member of each set of jointed arms. To one of these studs 9 is pivoted at h" a strip, as h, for each beater. This strip h is pivoted to a sliding sleeve, 71., on the reel-shaft, which sleeve has five lugs-one for each strip h. The power to open and close the reel is applied to the sliding sleeve h on the reel-shaft, to which motion is communicated through the medium of the forked piece '0 which enters a groove cut in the sliding sleeve. The forked piece 1' receives its motion through a rack, j, which is caused to reciprocate through the handwheel (for the operator) m, shalt Z, and pinion 70. By thus providing a pivot-point for the strip h at a short distance from thejoint, I am enabled to secure a quicker and easier opening or folding of the reel, because, as will be seen in the dotted portion of Fig. 1, where the reel is shown closed, it will require much less force to raise the part 0 when the moving force is pivoted at it than if it were exerted in adirect or nearly direct line with the piece 0. Suppose the reel to be in the partially-expanded position shown in Fig. 1, and it is desired to fold it completely, then the handwheel m will be turned in a proper direction to cause the rack j, fork i, and sliding piece h to move in the direction of the arrow across This will causethe piece h to move in the direction of the arrow across its face, and the other parts will each move respectively in the direction of the arrow across its face. Should it be desired to swing the reel as thus folded to the position shown in dotted lines, Fig. 1, or any other desired position, the pin a may be taken out of the part a and the top of that part swung back on its hinge a. The pin a may be taken out of the forked piece i and that piece swung out of the way on its pivot 0, when the reel may be lifted out of the piece a and swung into any desired position. Of course where more or less than five heaters are employed the parts may be altered to correspond, and still retain the features of'my invention.

\Vhat I claim as my inventiomand desire to secure by Letters Patent, is

1. In a folding reel for harvestingmachines, the combination, with a revolving shaft, of

beaters, two pairs of jointed arms connecting heaters, two pairs of jointed arms connecting each beater with the shaft, a strip, 6, for each beater, pivoted at one end to the outer'member of its pair of arms and at the other end to the shaft, a stud, g, mounted on the inner member of each pair of jointed arms adjacent to the drivers seat, a link, h, pivoted at one end to each stud and connecting the same with a reciprocating piece, and a stretcher connect ing the inner members of the two pairs of jointed arms connecting each beater with the shaft, substantially as set forth.
